Let's divide 787306 by 3
The aim is to understand the frequency of 3 in 787306.

Moving on to step 1:
When dividing 7 by 3, we get 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 6 from 7 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

On to step 2:
The number 3 fits into 18 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
The remainder is 0 after subtracting 18 from 18.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 3

Let's proceed to step 3:
7 divided by 3 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 262.0
Subtracting 6 from 7 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 3

On to step 4:
3 goes into 13 4 times with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 2624.0
The remainder is 1 after subtracting 12 from 13.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 3

On to step 5:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 26243.0
Subtracting 9 from 10 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 3

On to step 6:
3 can be fit into 16 5 times, resulting in a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 262435.0
Subtracting 15 from 16 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 262435.3
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
3 goes into 10 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 262435.33
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 262435.33 and a remainder of 0.001.
